Modern blast furnaces use bell-less top systems for the charging of the solid feed into the furnace.The complete potential of the charging system for distributing the material in the furnace cross-section in any desired pro?le can be achieved only by using a
suitable charge distribution model.By considering theˉow of di?erent types of solid particles like iron ore,sinter and coke through
the bin and rotating chute,equations have been developed for the particle trajectories.The formation of the ring shaped hill of
material by the accumulation of the falling material has been modeled considering the angle of repose,rolling and layer penetration.
These relationships have been combined with appropriate corrections for the burden descent and the mixed layer formation to
develop the overall geometry of the stock line.The burden charge model has been used in an optimization routine to determine the
best charging pattern to transit from an existing stock line geometry to a new geometry.The models have been tested in an oper-
ating furnace and incorporated in a supervisory control system.#2001 Elsevier Science Ltd.All rights reserved.

现代鼓风炉使用最少钟顶系统固体炉料运送到火炉,在任何专业完全有可能分配加料系统材料到火炉的横断面,ie可以通过使用一个合适的电荷分布模式,通过比较不同形式的固体颗粒像铁矿砂,烧结块和焦炭通过料仓和旋转的槽的行列,我们发展了颗粒轨迹方程式.考虑到再-放置,滚动和层渗透,通过不断落下的物料的堆积而形成的圆圈形的料堆形式被固定下来.这些关系已经包括了对重力下落和混合层形式的适当校正,以此来发展物料线的整体几何尺寸.重力加料模式已经用在优化的路线,来决定最佳的从已有的料线传送到一个新的料线上的加料方式.这种模式已经在一个实际工作的高炉上试验过,并结合了一个监督控制系统.
